Jan 26, 2019· SMAW. You can use SMAW, or stick welding, to weld through mill scale because the electrodes have deoxidizers and a slag system. Some stick electrodes are designed to offer better success when welding extremely thick scale or on very dirty base material. When you are welding moderate mill scale, any stick electrode is a good choice.
